Description

Annual species with wind-pollinated hermaphroditic flowers. Tolerates light sandy, medium loamy, and heavy clay soils across mildly acid to basic pH ranges. Requires full sun and prefers moist soil.

Edible Uses

Leaves can be eaten raw or cooked as a spinach substitute, though raw leaves should only be consumed in small quantities due to toxicity concerns. The seed can be ground into a powder and blended with cereal flours for making bread, cakes, and similar foods. Seeds are small and fiddly; soak them overnight and rinse thoroughly before use to remove any saponins.

Medicinal Uses

None known.

Known Hazards

The leaves and seeds of all members of this genus are more or less edible. However, many of the species in this genus contain saponins, though usually in quantities too small to do any harm. Although toxic, saponins are poorly absorbed by the body and most pass straight through without any problem. They are also broken down to a large extent in the cooking process. Saponins are found in many foods, such as some beans. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish. The plants also contain some oxalic acid, which in large quantities can lock up some of the nutrients in the food. However, even considering this, they are very nutritious vegetables in reasonable quantities. Cooking the plants will reduce their content of oxalic acid. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition.
